  • In view that traditional mining δ free sets algorithm exist generating candidate itemsets,traversing all direct subsets,and so on leading to low efficiency,a free sets determine lemma and a fast mining free sets algorithm FMFS were proposed.FMFS used Rymon setenumeration tree as searching space and combined with pruning strategy,and then used the free sets determine lemma to quickly determine the candidate itemset.Experimental results showed FMFS algorithm not only mined all free sets,but also showed better performance than existed mining algorithm.
